Tunnels and channels facilitate the transport of small molecules, ions and water solvent in a large variety of proteins. Characteristics of individual transport pathways, including their geometry, physico-chemical properties and dynamics are instrumental for understanding of structure-function relationships of these proteins, for the design of new inhibitors and construction of improved biocatalysts. CAVER is a software tool widely used for the identification and characterization of transport pathways in static macromolecular structures. Herein we present a new version of CAVER enabling automatic analysis of tunnels and channels in large ensembles of protein conformations. CAVER 3.0 implements new algorithms for the calculation and clustering of pathways. A trajectory from a molecular dynamics simulation serves as the typical input, while detailed characteristics and summary statistics of the time evolution of individual pathways are provided in the outputs.
MDAnalysis documentation¶ Release: 0.19.2 Date: Nov 08, 2018 MDAnalysis (www.mdanalysis.org) is an object-oriented python toolkit to analyze molecular dynamics trajectories generated by CHARMM, Gromacs, Amber, NAMD, LAMMPS, DL_POLY and other packages; it also reads other formats (e.g., PDB files and XYZ format trajectories; see Table of supported coordinate formats and Table of Supported Topology Formats for the full lists). It can write most of these formats, too, together with atom selections […]
http://www.charmm-gui.org/?doc=input/ligandrm Primero debemos cerciorarnos que el ligando corresponde, y no forma anillos anexos como es el caso, de AS4 dentro del PDB, cargamos Ligand ID as4, y vemos la conformación correcta, para luego seguir al siguiente paso.. Next. Tomamos el ligando AS4, que ahora se llamara LIG comprobamos la estructura del ligando Does not show […]
